A one-cup serving of spaghetti with meatballs contains 260 calories and 32 grams of carbohydrates. a one-cup serving of chopped iceberg lettuce contains 5 calories and 1 gram of carbohydrates. determine how many servings of each would be required to obtain 135 calories and 17 grams of carbohydrates.

A cup of chopped iceberg lettuce contains 5 calories and 1 gram of carbohydrates.
If we subtitute those amounts from 135 calories and 17 grams of carbohydrates, the remaining will be 130 calories and 16 grams of carbohydrates.
Since, a cup of spaghetti with meatballs contains 260 calories and 32 grams of carbohydrates, a half cup will have 130 calories and 16 grams of carbohydrates.
Hence to obtain 135 calories and 17 grams of carbohydrates, the person should take one cup of chopped iceberg lettuce and half cup of spaghetti with meatballs.
